Emerging language (EL) is any unplanned language item that arises naturally during lessons that the teacher then chooses to focus on for clarification or modification. Working with Emergent Language highlights the importance of EL and makes the argument that focusing on it is an essential part of learning a language and therefore a skill that every language teacher should possess or work to develop. However, working with EL is thought to be a very difficult skill to master, and as a result is rarely covered on training courses or in teacher development products. This book seeks to close this gap by making the reader more aware of what EL is and how they can learn to work with it more effectively and confidently through awareness raising, practice, and reflective tasks.
